Storage Redundancy (1 / 16):

Your company operates in a region with stringent data governance laws that restrict the replication of data outside the country borders. Their core application requires a large volume of data storage but this data can be regenerated easily if any data loss occurs. Recently, they have decided to migrate their application to the Azure cloud and are considering their options for storage redundancy, considering costs.

What type of storage redundancy should your company consider for their application? Why?
In their context, what could be a potential issue if they choose geo-redundant storage (GRS) over the recommended storage type?
Considering their data governance requirements, how would the concept of paired regions apply or not apply in their scenario?

Answer:

Your company should consider using Locally Redundant Storage (LRS). LRS would be suitable as it allows data replication within the same region which meets the company's data governance requirements. Also, since the data can be regenerated easily in the case of data loss, LRS would be a cost-effective choice.
If they choose Geo-Redundant Storage (GRS), they might violate data governance laws because GRS replicates data to a secondary, geographically distant region, which might be in a different country.
Paired regions don't apply in this scenario because the data can't be replicated outside the country or region due to data governance requirements.
